Abstract

A ceramic cutting insert, including a face ground top surface, and at least one peripheral clearance surface adjacent to an edge, from which a reinforcing chamfer surface extends inward. The chamfer surface forms a first acute angle with a reference plane that is parallel to the top surface. A generally concave unground intermediate surface is formed between the top surface and the chamfer surface, the intermediate surface at the transition to the top surface forming a second angle with the top surface that is greater than the first angle, and the width of the chamfer surface being greater than the width of the intermediate surface.
